Are dark thoughts are good for me?

Everyday, every minute, and even recently.

All I think of are dark thoughts and my mood has become darker. I think this is actually good for me and every time I go to the dark thoughts it makes me more stronger in life. Is this weird?

Every time some really good friends I've made have tried to push me out of it irl, the thoughts come back rushing stronger. Been happening since 11 and I feel like I benefit from these thoughts because it makes me a stronger/aware minded person.

Is this ok for me to do or no? It has made me trust people less but be able to still make think I'm their friend. Not saying in general but I feel like dark thoughts have always been good for me and when others try to push them out it just makes me more angrier.

I've been to therapy multiple times and there is no way to change this it feels like its become a part of me now.

TLDR: Dark thoughts have always swirled in my head and I feel like they are the best thoughts to keep as they have made me a stronger individual.
